| 摘 要： | 在传统的Rose-Fowler-Vaisberg(RFV)模型基础上引入辐射激发项，解释了辐射感应电导率与辐射剂量率的指数关系及范围.利用改进后的模型分析了不同辐射条件下材料感应电导率的变化情况，其结果表明，辐射剂量率主要影响感应电导率的大小，对感应电导率的整体变化趋势无显著影响，决定感应电导率长时间衰减的是材料载流子复合率.

| Abstract: | By introducing a new term into the traditional Rose-Fowler-Vaisberg model, The exponential relationship between radiation induced conductivity and dose rate is explained. The evolution of radiation induced conductivity under different radiation conditions are also analyzed. The result indicates that dose rate mainly changes the magnitude of radiation induced conductivity while the long-time decay of radiation induced conductivity is determined by carrier recombination rate of the material. |
